Patented Oct. 25, 1932 PATENT OFFICE WILLIAM r. aYLNbEB, or SAN mecs,frans MATTRESS-SUPPOBNTING SPRING' COVER Application led December 29,1930. Serial No. 505,390.

The invention aims to provide a new and improved device for covering bedsprings, particularly those embodying vertical coils, for the purpose ofpreventing any portions of the mattress from having a tendency to vyieldinto the u per ends of the-coils. Hence, the device is o particularadvantage in connection with inner spring mattresses, for the springsthereof are of much smaller diameter than the coils of the bed spring,with the result that all of the mattress springs lying within thecircumference of any of the relatively large coils of the bed spring,are

not basicly supported by any portion of said 5 bed spring, the resultbeing that the-inner springs of the mattress have a tendency to cant andotherwise move out of proper relative-positions, severely chaing theside walls of the pockets in which they are conlned and eventuallynecessitating mattress repair or replacing. Such diiioulty is entirelyovercome by the present invention which provides substantially uniformbasic support for all of the inner springs of the-mattress.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, description being accomplishedby reference to the accompanying drawing. 30 Fig. 1 is a top plan viewshowing one form of construction for illustrative purposes.

Figs. 2 and 3 are respectively longitudinal and transverse sectionalviews on lines 2-2 and 3 3 respectively of Fig. 1.

Fig. 4 .is a fragmentary perspective view. Fig. '5 is a diagramillustrating the relaltion of the coils of a bed spring and an innerspring. mattress, and illustrating the manner in which the supportingmembers emsubstant-ially uniform basic support of' the inner springs ofthe mattress. d

Fig. 6-is a -detail elevation showing one of many variations with whichthe spring-supporting members may be constructed.

bodied in the present invention, provide forr A preferred way lofcarrying the invention into eifect, has `been herein illustrated andwill be specifically described, but it is to be understood that withinthe scope of the invention as claimed, numerous variations may be madeover the present showing.

The numeral 7 denotes a ilexible two-ply sheet of any desired materialwhose two plies are preferably formed of separate pieces. The two pliesof this sheet are stitched together on parallel transverse lines 8 andon two longitudinal lines 9 to provide said sheet with a plurality ofelongated pockets 10 and the edges of the sheet are stitched together at9. Obviously, the pockets 10 may extend entirely to the ed es of thesheet 7 or may terminate inward y of said edges, the latter constructionbeing herein shown.

Disposed longitudinally within the pockets 10 are spring-supportingmembers 11, preferably formed of resilient wire. These members may belongitudinally straight as shown in Fig. .1, or may have undulated por`tions such as 12 of Fig. 6, or may be of an other preferred shape.Preferably the en s of each member 11 are bent to provide loops 13,'which loops are preferably although not necessarily circular. Theseloops hold the ends of the members 11 properly positioned within thepockets 10 and while in most instances, the intermediate portions ofsaid members will remain centered within the pockets, even if saidmembers be straight, the undulated portions 12 may be used if desired,to positively hold said intermediate portions of said members 11 againstlateral shifting in the pockets. r

The wires or other members l1 are so closely spaced that a plurality ofthem will span any of the relatively large coils 14 of a conventionalvertical coil bed spring, as seen in Fig. 5, and said wires or othermembers 11 are preferably so closely spaced that each comparativelysmall vertical coil 15 of a conventional inner spring mattress, will bedirectly supported by at least one of said members 11, as alsoillustrated in Fig. 5. Hence, the members 1l held in the proper spacedrelation, provide for substantially uniform basic'support of all of themattress coils 15, and consequently hold these coils in their truepositions, overcoming danger of their injuring the pockets in which theyare conined. Even if the members l1 be used under a mattress whichembodied no coil springs, they will still be of advantage, in that theywill prevent all portions of the mattress from yielding downwardly belowthe portions of the bed spring with which they contact, thus providing amuch more uniform basic support for the mattress and consequentlyminimizing wear.

The construction herein disclosed provides means for holding thespring-supporting members 1l in the required spaced relation and meansfor hingedly connecting said members with each other to allow rolling ofthe connected members and to permit relative movement thereof in use.Then too, the construction illustrated provides a sheet which isflexible longitudinally but is tranverely stiii'ened by ribs. These endscould of course be attained in ways other than the particular exampleherein given and hence attention is again invited to the fact that suchvariations may be made within the scope of the invention as claimed.Moreover, although I have herein described the invention for use withsprings and mattresses, it will be clear that the same general structurecould be used for other purposes, for intance, in the manufacture ofwindow blinds and shades. Hence, such uses are contemplated and theWordmgherein used in describing and claimlng the invention is to beconstrued accordingly.

I claim 1. A mattress-supporting spring cover comprising a plurality ofhorizontal supporting members, and a iiexible sheet having individualelongated pockets in which said members are disposed, said members beingformed of wire and having laterally bent portions holding them properlypositioned within said pockets.

2. A mattress-supporting spring cover comprising va plurality ofhorizontal supporting members formed of wire and having their endsbentto provide loops, and means holding said loops in substantially abuttingrelation vand hingedly connecting them.

3. A mattress-supporting spring cover comprising a plurality ofhorizontal supporting members formed of wire and having their ends bentto provide loops, and a flexible sheet'having individual pockets inwhich said members and their loops are disposed, said loops holding saidmembers properly positioned within said pockets.

4. A mattress supporting Vand protecting device adapted to lie upon aconventional vertical-coil bed spring, said device comprising a flexibleunbroken sheet to cover the bed spring, said sheet being provided with aplurality of closely related pockets extending substantially fromedge-to-edge thereof, 'and a multiplicity of spring wires extendingthroughout the length of and disposed within said pockets, said springwires being so spaced that a plurality of said wires will span the upperend of each vertical coil of the bed spring to prevent 'portions of themattress from settling into said coils, the flexibility of said sheetand the resiliency of said spring wires 4allowing free yielding of thedevice with the mattress and the bed spring without impairing theeiliciency oi either said mattress or said bed spring.

In testimony whereof I alix my signature.

WILLIAM P. RYLANDER.
